NTE8065 thru NTE8242 Thermal Cutoff (Thermal Fuse) Description: Twenty One Thermal Cut-offs (also known as Thermal Fuses) are now included in the NTE product line. They are miniature, NON-RESETTABLE temperature sensitive devices designed to prevent appliances and electronic equipment from overheating. NTE thermal cutoffs are UL and CSA listed. Literally thousands of different applications have been devised for thermal-cutoffs, thus providing a large replacement market. Such applications include: * Hair Dryers * Refrigerators * Battery Chargers * Toasters * Irons * Hot Plates * Glue Guns * UPS * Electric Motors * Window Fans * Coffee Makers * And hundreds of others * Microwave Ovens * Popcorn Poppers * Dishwashers The TCO (Thermal Cut-Off) responds to temperature by interrupting an electrical circuit when the operating and/or environmental temperature exceeds the thermal rating of the device. This is accomplished when the internal organic pellet experiences a phase change, allowing the spring activated contacts to permanently open the circuit.

Holding Temperature: The maximum temperature at which the thermal cut-off can be maintained while conducting the rated current for 168 hours which will not cause a change in the state of conductivity to open the circuit.

Do not store above +48C (+120F). Note 2: Color Band does not denote temperature group. Note 3: The electrical resistance of the NTE series thermal cut-off is comparable to that found in an equal length of 18 gauge solid copper wire. With proper air flow, heat generation below 15 Amps is minimal, above 15Amps the upper limit on the current capacity will depend on the environment for each specific application. Note 4: A general rule of thumb for continuous operating temperature for thermal cut-offs is 30C less than the Maximum Opening Temperature. Rev. 3-19
